[0018] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0019] The utility model discloses a vehicle-mounted wireless charging module, see Figure 1 , which includes a loading part 1, an upper shell 2, a power coil 3, a shielding cover 4, a printed circuit board 5, thermal conductive silicone 6, a lower shell 7 and a fan assembly 8.

[0020] The loading part 1 has a placement cavity 11 for placing the device to be charged, which is arranged outside the upper shell 2. The loading part 1 and the upper shell 2 can be an integral part, and the placement cavity 11 can be composed of the loading part 1 and the upper shell 2. On the top surface of the placement cavity 11, there is a clamping mechanism 12, which can at least move along a fixed axis. The clamping mechanism 12 has a part extending into the placement cavity 11 to fix the device to be charged.

[0021] See also Figure 2 and Figure 3 , an optional clamping mechanism 12 is described. The clamping mechanism 12 comprises: a first arm 121, a second arm 122, a torsion spring 123, a limiting groove 124 and a fixed shaft; one end of the first arm 121 is rotatably disposed on the fixed shaft, and the torsion spring 123 is sleeved on the fixed shaft for resetting the first arm 121; one end of the second arm 122 is rotatably connected to the other end of the first arm 121, and the other end of the second arm 122 is slidably disposed in the limiting groove 124.

[0022] In one example, the clamping mechanism 12 has a clamping state and an unlocking state; the clamping state is: the first arm 121 rotates along the fixed axial placement cavity 11, and drives the second arm 122 to slide out of the limiting groove 124; the unlocking state is: the first arm 121 rotates along the fixed axial placement cavity 11 outside, and drives the second arm 122 to slide into the limiting groove 124.

[0023] When no mobile phone is placed, it is in the unlocked state. After the mobile phone is placed in the placement cavity 11, the first arm 121 or the second arm 122 is pressed from outside the placement cavity 11, that is, from the top of the loading part 1, so that it forms a clamping state. This method is applicable to a variety of mobile phone thicknesses. When taking out the mobile phone, the mobile phone is directly pulled out, and the friction between the mobile phone and the first arm 121 or the second arm 122 brings the clamping mechanism 12 into the unlocked state.

[0024] In another example, the clamping mechanism 12 is normally in a clamping state, and the torsion spring 123 provides a holding force. After the mobile phone is placed in the placement cavity 11, the first arm 121 is pushed to rotate along the fixed axis toward the outside of the placement cavity 11, and the second arm 122 is driven to slide into the limiting groove 124. This method is also applicable to mobile phones of various thicknesses.

[0025] Regardless of the above examples, the first arm 121 and the second arm 122 have a surface facing the placement cavity 11 that is a curved surface.

[0026] Preferably, the vehicle-mounted wireless charging module further includes a shielding cover 4, which is arranged between the upper shell 2 and the lower shell 7 and is located below the power coil 3. Preferably, it also includes a printed circuit board 5, which is arranged between the upper shell 2 and the lower shell 7 and is attached to the lower shell 7 through a thermally conductive silicone 6.

[0027] Preferably, it further comprises a fan assembly 8, which is arranged on the upper shell 2 or the lower shell 7 and forms an air guide channel. Preferably, the fan assembly 8 has at least two upper and lower air inlet channels 81 and a lateral air outlet channel 82, and the air outlet channel 82 is connected to the air guide channel. Figure 1In the embodiment shown, the fan assembly 8 is integrated with the upper shell 2 and is disposed on the side of the upper shell 2. When the loading member 1 and the upper shell 2 are separate structures, the placement cavity 11 has an air duct that is connected to the air outlet channel 82.

[0028] Compared with the single air inlet channel in the prior art, the air volume and air pressure can be increased by about 20%. The heat dissipation effect is significantly improved. Table 1 below uses data of a single air inlet channel, and Table 2 is the data of this application using two air inlet channels.

[0034] Preferably, one of the upper shell 2 and the lower shell 7 is provided with a slot, and the other is provided with a buckle, and the two are connected and installed. This can reduce the number of screws used and the installation process. At the same time, the sheet metal lower shell 7 replaces the die-cast lower shell in the prior art, saving material costs, manufacturing process costs, and assembly costs.

The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings.
